Getting Attempting to unwind past bad PC Error

[Vincent Paul S]

Hi,

I am getting "Attempting to unwind past bad PC" error in 64 bit Itanium processor HP-UX.

Below is the stack trace:

This forum is for PA workstation hardware. I've asked the moderators to move this to HP-UX > languages.

Are you debugging this on the same system that produced the core file? What happens if you run the application in the debugger?

You should download a newer version of wdb to see if can give an idea what function or shlib is having the problem.
Can you try "info shared"? You may be in dld.so.

Using -mt option in aCC compiler flags worked.
